| Abstract | Service-oriented architecture (SOA) is the premier application framework for integrating complex heterogeneous computing systems in business and government. To utilize SOA in sensitive military systems, however, the issue of multi-level security (MLS) must be addressed. MLS requirements call for strict separation and limit interaction between classification levels. However, many Web services and resources reside in the Low domains. Support services such as weather forecasting, mapping, and procurement typically reside in the Unclassified level. There is strong desire from High clients and applications to make use of those services. This paper presents a framework for adding MLS capabilities to SOA systems. Specifically, it will allow clients in High to securely and transparently utilize resources in Low. It addresses MLS requirements by minimizing the potential risks for information leak and thwart inference attacks. It also provides privilege control capabilities to limit and manage interaction between High and Low at the infrastructure level. Since an overt channel is created from High to Low, cross domain SOA has to be used with caution where the functional benefits outweigh the security risk. MLS-SOA is a practical solution that leverages the existing MLS infrastructure and augments security. Cross-domain solutions (CDS) already in place will mediate traffic across domain boundaries. MLS-SOA will provide additional safeguards and control for domains, applications, and users in High that need to invoke services across domain boundaries. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
